As an aside, I have a fairly large (~50,000 line) matrix library that I am trying to figure out how to license, GPL or LGPL. Ideally I'd like to contribute to Lazarus/FPC. The library includes optimized code for 2D and 3D vector graphics, operator overloading, sorting, etc. On top of that is a vector graphics library with bitmap (working with BGRABitmap), svg, eps, dxf output, that includes layers, and many other options. If anyone with numerical or graphics experience has suggestions I'd be interested in a conversation.
